I'm kind of wagon guy.
Personally I prefer wagon to suv or minivan.
I used to drive mini clubman and volvo v70 and I really love them.
But when I drove BMW 5 Wagon it even gave me a joy of driving too. Feels very sporty and sharp at corners. And very spacious and comfy.

But some parts are very pricey especially the battery.
If common problems with 5 series are being taken care of, this 5 series wagons will never disappoint you.
